The rain caused heavy traffic, delays and minor accidents during the evening commute Wednesday. After the rain moved out, fog remained. A Dense Fog Advisory is in effect for the North and West suburbs until 7 a.m. Thursday with visibility 1/4 mile or less. The fog is especially thick in areas that still have snow cover so be careful driving.

Our rain totals on Wednesday were not particularly large with less than an inch falling throughout the region. However, when you combine that rain with the melted snow, it’s not difficult for the rivers to start rising or for there to be localized street flooding.

As of now, most of our rivers are forecasted to be close to flood stage, but not above it. One exception is the Schuylkill in Norristown, which is expected to crest nearly one foot above flood stage. That could cause flooding problems in West Conshohocken and West Norriton.
